4 THE LAW OF STORMS. 



of a Polar and an Equatorial current, twice during 

 the year. Therefore they are N. E. and S. W. in 

 the Northern Hemisphere; and S. E. and N. W. in the 

 bouthern Hemisphere. 



The S. W. passage winds of the Northern Hemis- 

 phere, and the N. W. passage winds of the Southern 

 Hemisphere, are Equatorial currents. 



Bodies of air set in motion from a state of rest, 

 turn the wind-vane in the direction of the meridian 

 as follows : 



The Polar current in the Northern Hemisphere from 

 N. toE. 



The Polar current in the Southern Hemisphere from 

 S. to E. 



The Equatorial current in the Northern Hemisphere 

 from S. to W. 



The Equatorial current in the Southern Hemisphere 

 from N. to W. 



In general the winds in the Northern Hemisphere 

 are as follows: 



Those from N. to E. the Polar currents. 



Those from E. to S. the transition of the Polar to 

 the Equatorial. 



Those from S. to W. the Equatorial current. 



Those from W. to N. the transition of the Equatorial 

 to the Polar. 



Also, in the Southern hemisphere, the winds are as 

 follows : 



TJiose from S. to E. the Polar currents. 



Those from E. to N. the transition of the Polar to 

 the Equatorial. 



Those from N. to W. the Equatorial current. 



Those from E. to S. the transition of the Equatorial 

 to the Polar.
